Well weird i am using CUP terrains too. And Takistan is not working fine. There always some installations as road lights, fireplaces, graves, sheds, and others.

In launch parameters add -malloc=system

My server has crashed once but when i have set allocator to "system" server is not crashing anymore.

Well i assume there are no possibility to blacklist that objects by staticData or whatever. I need to blew up the whole place. I have created script that blew up all "houses" in range 20m. But when f.e. object is a "grave" (which is happen once) it cant be destroyed. Is there any other possibility to send notify to players when installation objects are destroyed and removed from OPCOM_instances? Are there such event handler or something what could be used in easiest way that the script does??

This behavior looks like poor fps on server. Check your server FPS.

This is strange i am already playing on takistan with the same version of ALiVE and CUP terrains/core and everything that you posted works perfect.

Yes same here. There are only one problem. Streetlights and others weird objects being picked up for some installations.

Thanks Spyder works perfect.

There no errors. Its simply pick up a street lamps and other weird objects as building. Spyder you are right.
cursorObject isKindoF "house" or cursorObject isKindoF "building" on them returning true .

The goal is how to blacklist them?

Takistan map.
